1n the 01d design and construction of revcr110ratory furnaces Where tie rods over the 11111111100 top were employed to tie one enel 111E the furnace to advanta 1011 were expermncec The construction was gxpensie. iiecessnatingl a large 111111111111' 111 iron rods of large di11meter,1rhich rods 1111011111011 space over the top of the' fur- To' afford a 60 111V t1e rods or 55 the other end` many dis- 30 nace 111111 thercot71 interfered with repairs to 85 11110 11n-nace root.

111th thel proposed construction the tiered system is eliminated and a cheap and strong tie member obtained. At the saine time valuable head room'or working space is -90 111111111011 for repa1r's to the furnace roof. l `11rtherrnore addtionad support to the main 111'011 1s provided.

claimt- 1. The combination with a revcrberatory furnace, of frame constructions bearing on opposite ends o1? the furnace, latera1 skewback plates for supporting the arch of the 11n-nace and connected with the said 4frame c11nst111ct1ons to serve as ties therebetween.

2. The Qombnation with a reverberatory furnace, of ranie constructions bearing on opposite ends of the furnace, lateral skewback plates Jfor supportingthe arch of theA `furnace' and means for intercon11e0ting1r the skew-back plate and the frame c i11str';.,ctions yfor placing the oriner under tension to serve as ties between the latter.

3. Arrangement according to"`cla1n1 2 in which each rrame construction` includes a 10 furnace having atplurality of frame elements extending' transversely of the furnace end in parallel relation and beams bearinf,r against the ysaifl frame elements and connected to the skew- 5 back plates.

4. Arrangement according to claim 2 in which the interconnecting means includes braces.

5. The-combination with a rei'erberatory one end a secondary chamber extending above the marin arch, a frame construction bearing against the end 'Lese-,02e

0i the. secondary ebambm: a [ranno wonstrnvtion beariner against ibo opposite ein] of the Furnace, lateral skew-bark plates and nicans for interconneting' the i\'e\\back plates and said frame eonstrlH-tions incilnb.

in ebraves extendingy from the skmv-back plates to points above the secondari7 Obambcr and tie rods for'intcreonnm'ting' the braces and the iframe construction bearing against the end of the secondaryv Chamber.
